摘要

空气分布现象对热环境研究及其有效性非常有用。这项研究的主要目的是检查和发现内部区域及其热环境的热特性。研究实验工作在博帕尔政府女子理工学院一楼实验室进行。实验分别在夏季和冬季进行,在一个封闭的空调房间内布置了空调空气排放管道。空调空气通过垂直设置的圆形管道排出。风管的垂直位置不同,分别为下风管 (L)、中风管 (M) 和上风管 (U)。本实验研究了上述试验室内的送风速度和垂直温度变化效果。实验结果分别在下风道、中风道和垂直风道开启条件下收集。试验室空间内距离风管出口各 1 米处的多个点记录了垂直温度变化和风速。结果表明,室内热环境和垂直温度分布受到排风管道位置和送风速度的影响。当测量测试点的位置靠近排风管道时,温度曲线会受到垂直方向的影响,并且在远距离测量时,温度曲线会变得相当一致。

An Experimental Study for Air Temperature Distribution in a Conditioned Room Using Various Vertical Locations of Conditioned Air Ducts
The Air distribution phenomenon is most useful in thermal environment study and its effectiveness. The main aim of this investigation is to examine and discover the thermal properties of the inside area and its thermal environment. The experimental work for research was studied at the first-floor lab of the government women’s polytechnic, Bhopal. The experiment was conducted in the summer and winter seasons in a closed-conditioned room with the arrangement of a conditioned air discharge duct. The conditioned air was discharged through the circular pipe duct which was set vertically. The duct has arrangements to discharge the air through various vertical positions as the lower duct (L), middle duct (M), and upper duct (U). This experimental work investigates supply air velocity and vertical temperature variation effectiveness inside said test room. The experiment results were collected with lower, middle, and vertical duct opening conditions respectively. The vertical temperature variation and air velocity at the outlet of the duct were noted with considerable points at 1 m from each inside the test room space. The outcome of the results shows the indoor thermal environment and vertical temperature distribution were affected by the discharge air duct position and supply air velocity. The temperature profile vertically impacted when the measuring test point position was near the discharge air duct and it became quite consistent in respective measurements from a large distance.
